以莱阳梨（Pyrus bretschneideri Reld cv.在0-2 ℃冷藏210 d期间，对两种不同透氧性和透CO2性的低密度聚乙烯（LDPE）包装膜在添加和不添加1-MCP（0.5 μ L/L和1.0 μ L/L）的情况下进行了评价。结果表明，0.5 μ L/L1-MCP+微孔膜包装能较好地保持莱阳梨果实的色泽、硬度、可滴定酸和Vc含量，是莱阳梨最适宜的冷藏处理。0.5 μ L/L 1-MCP+微孔膜包装处理抑制了果实的呼吸和乙烯释放，维持了超氧化物歧化酶、过氧化物酶和过氧化氢酶的活性水平，降低了细胞膜透性和丙二醛含量，抑制了脂氧合酶和多酚氧化酶的活性。(C)2013爱思唯尔有限公司版权所有。
To identify the most effective modified-atmosphere packaging (MAP) and/or 1-methylcyclopropene (1-MCP) treatment to maintain the fruit quality of 'Laiyang' pear (Pyrus bretschneideri Reld cv. Laiyang) during 210 days of cold storage (0-2 degrees C), two kinds of low-density polyethylene (LDPE) packaging films with different O-2 and CO2 permeabilities were evaluated with and without 1-MCP (0.5 mu L/L or 1.0 mu L/L). The results showed that 0.5 mu L/L 1-MCP plus micro-perforated film packaging maintained the color, firmness, titratable acidity, and vitamin C content of the fruit flesh and was the most appropriate treatment for 'Laiyang' pear fruit during cold storage. Treatment with 0.5 mu L/L 1-MCP plus micro-perforated film packaging inhibited respiration and ethylene production; maintained the activity levels of super oxidase dismutase, peroxidase, and catalase; decreased the cell-membrane permeability and malondialdehyde content; and inhibited the lipoxygenase and polyphenol oxidase activity of the fruit during cold storage.
